Description

Technical Field

[0001] The present invention relates to the technical field of offshore aquaculture equipment, and in particular to a deep-sea truss-type semi-submersible aquaculture device. Background Art

[0002] With the continuous improvement of protection measures for the nearshore marine environment, it has become a trend for fishery farming to move to the deep sea. The quality of aquatic products from deep sea farming is good, and large deep sea cages have become the main carrier of large-scale deep sea industrial farming equipment.

[0003] At present, ordinary aquaculture enterprises or individuals still mainly use the circular HDPE wind and wave resistant aquaculture nets introduced from Norway. Since the cages cannot dive and are mainly gravity-fed, the floating bodies on the water surface are large, and only some shallow fish can be cultured. They are greatly affected by wind and waves, and the shape of the cages becomes larger, making it impossible to truly engage in deep-sea aquaculture.

[0004] There are also some lifting aquaculture equipment as shown in technical proposal 201610113360.1, which adopts direct suspension of the upper frame, and multiple lifting mechanisms are arranged on the frame for lifting. The electrical insulation protection and synchronous lifting control of the electrical appliances arranged in multiple positions are difficult, and the floating ring on the water surface is large in volume and has poor wind and wave resistance. When used in deep sea areas, the suspended structure is easily damaged, and the cage is difficult to lift evenly. Moreover, the float can only be maintained in the area near the water surface, the buoyancy of the cage is limited, and the reliability of the equipment is weak. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a deep-sea truss semi-submersible aquaculture device, which is mainly made of corrosion-resistant, high-strength, lightweight materials such as polymer PE, glass fiber, and carbon fiber composite materials, and solves the problems of poor anti-sinking and wind and wave resistance of the cage platform, poor material corrosion resistance, etc. with lightweight and high-strength materials; the lightweight pipe material block mode is convenient for transportation and installation, and because the pipe itself is buoyant, it is convenient for on-site assembly, and there is no need to return to the factory for repair in the later operation and maintenance, and no secondary anti-corrosion coating is required. The material can be recycled and reused for environmental friendliness, etc., to solve the problems of high requirements for the production site of the steel truss semi-submersible aquaculture platform in the prior art, and the anti-corrosion, rust removal and painting need to be returned to the factory for inspection and maintenance, and large tugboats are required for towing, which is costly, time-consuming and labor-intensive; it is also possible to add the swing arm type floating body assembly of the present invention to the existing wind and wave resistant HDPE aquaculture cage, and then partially transform it to increase the diving function, reduce the deformation of the cage, and increase the wind and wave resistance.

[0006] The present invention provides a deep-sea truss-type semi-submersible aquaculture device, comprising a centralized control buoyancy cabin, a truss structure float, a counterweight column, a mooring cable, a culture cage and a swing arm float assembly;

[0009] One end of the mooring cable is connected to the truss structure floating body, and the other end is anchored on the seabed;

[0010] The breeding cage is installed on a truss structure float;

[0011] The swing arm type float assembly includes a swing arm bracket, a float buoy, a guide wheel, a rope chain tensioner and a float rope chain. One end of the swing arm bracket is hinged to the upper floating ring of the net cage float, and the other end is connected to the swing arm float. The guide wheel is arranged at the bottom of the lower floating ring of the net cage float. The rope chain tensioner is arranged above the upper floating ring of the net cage float. One end of the float rope chain is connected to the swing arm type float buoy, and the other end is connected to the rope chain tensioner through the guide wheel.

[0012] As a preferred embodiment of the present application, it also includes a partition baffle, which is arranged in the upper floating ring and the lower floating ring, and divides the hollow structure of the upper floating ring and the lower floating ring into a number of pressure water tanks, and the centralized control valve is connected to each separated pressure water tank through a pipeline.

[0013] As a preferred embodiment of the present application, the number of the centralized control valve distribution valves is adapted to the number of the cage floats and the swing arm float pressure tanks.

[0014] As a preferred embodiment of the present application, it also includes a pedal and a guardrail, and the pedal and guardrail are installed on the swing arm bracket.

[0015] As a preferred embodiment of the present application, a backup battery is provided in the centralized control buoyancy compartment, and the backup battery is electrically connected to the cable retracting and releasing tensioner.

[0016] As a preferred embodiment of the present application, the centralized control floating chamber also includes a feeder, and a feeding port of the feeder is arranged in the breeding cage.

[0017] As a preferred embodiment of the present application, the gas delivery device is a compressed gas cylinder or an air pump.

[0018] As a preferred embodiment of the present application, the truss structure float also includes a counterweight column, which is connected to the upper floating ring and the lower floating ring. The column is a hollow pipe with a conical sealing block at the lower end. The sealing block is connected to the cable collector through a towing rope, and the upper end is open to facilitate the loading of counterweight material.

[0019] As a preferred embodiment of the present application, a water inlet valve and a water outlet valve are provided on the swing arm type float, and the water inlet valve and the exhaust valve are connected to the centralized control valve distribution valve through pipelines for electric or pneumatic opening and closing.

[0020] As a preferred embodiment of the present application, the cage float adopts a hollow pipe made of PE or glass fiber or carbon fiber composite material.

[0021] Different from the prior art, the above technical solution has the following advantages:

[0022] 1. Inject air or seawater into the hollow ballast tank of the truss cage float to achieve the ability to drive the aquaculture cage to float to the water surface and dive as a whole. The truss cage has a large aquaculture space. Under the action of ocean currents, the entire cage can maintain stable tension, ensuring the activity space of the aquaculture organisms, reducing the injury of the aquaculture fish scales scratching the net, increasing the aquaculture water body and selecting the aquaculture water layer.

[0023] 2. Several swing arm buoy assemblies are hinged on the buoyancy ring of the truss cage float, which can realize three functions of the truss cage: lifting, semi-submerged, and deep-submerged. In the lifting state, the cage can be shifted and towed as a whole, and the net can be repaired, cleaned, replaced, and the farmed organisms can be harvested on site; in the semi-submerged state, the cage can be fed and observed; in the deep-submerged state, the cage can resist typhoons, avoid red tides, adjust water layers, and adjust water temperature.

[0024] 3. Add or reduce counterweights at the upper port of the counterweight column to overcome the buoyancy of the aquaculture cages themselves, adjust the diving depth of the aquaculture cages, adjust the water temperature and oxygen content, and avoid the damage to aquaculture organisms caused by red tides in summer and low temperatures in winter, increase the survival rate of aquaculture organisms, increase production and increase income, and increase the types of aquaculture organisms by adjusting the water depth. The aquaculture cages can be lifted and submerged, giving full play to the ability to save aquaculture water and improve the three-dimensional use of the sea.

[0025] 4. A centralized control buoy is installed on the middle guide column of the truss-type deep-diving cage. By setting a backup battery in the centralized control buoy, it is convenient to provide uninterrupted power supply to electrical equipment and various sensors, providing effective information for digital scientific breeding.

[0026] 5. The feeder is arranged in the centralized control buoyancy cabin, and the feeding end of the feeder faces the aquaculture cage. In extreme weather, the feeder can be used to feed bait, and in normal weather, the aquatic products in the aquaculture cage can be fed regularly and quantitatively, reducing the labor intensity of the aquaculture staff.

[0027] By using compressed gas cylinders or air pumps as gas delivery devices and controlling the opening and closing of valves through pipelines, the ballast tank water is controlled.

[0028] The blocking plate is arranged in the hollow structure of the net cage float and divides the hollow structure of the net cage float. The centralized control valve is communicated with the ballast tanks of each separated hollow structure of the net cage float through the distribution valve and the pipeline. The anti-sinking property of the hollow structure of the net cage float is increased by the setting of the blocking plate. The number of distribution valves of the centralized control valve is adapted to the number of partitions. After the partition of the net cage float partitions, it is convenient to quickly adjust and handle the ballast situation, and improve the convenience and accuracy of the lifting operation. The net cage float is provided with an upper connecting port, a lower connecting port and a lower control valve. The upper connecting port is arranged at the upper part of the net cage float and is connected to the centralized control valve distribution valve through a pipeline. The lower connecting port is arranged below the net cage float. The lower control valve is arranged on the lower connecting port to connect the upper and lower floating ring ballast tanks of the truss-type float through pipelines.
